BC-TRV BCTRV BC-TRW W TRV Camera Battery Charger for Sony：NP-FP50 FP70 FP90 NP-FH50 NP-FH70 NP-FH100 NP-FV50 NP-FV70 NP-FV100 FV50 FV70A FV100A Travel Charger Power Supply Cord

Another person mentioned that the charger would turn and off, especially if you jiggle the battery. The problem is that the connection fingers are a bit crusty and it wasn't working well, I also had the same problem. Here is the fix: I found that a bit of DeoxIT cleaned out the crud on the connection. Just get a small bottle of DeoxIT and dip the brush with the DeoxIT on to the connector, then put the battery in the charger and remove the battery and put it back into the charger - do this several times (10 times?) It should have a good connection now. My guess is that some the shipping was very slow over the ocean - causing some of the salty air to get into some packages. Other than that, it works fine for me. Here is the link to DeoxIT: https://www.amazon.com/D100L-16BX-DeoxIT-D100L-Mini-Brush-Applicator/dp/B07F8ZX2GD/ref=sr_1_4?crid=3DGJTOWER2VFD&keywords=DeoxIT&qid=1707178445&sprefix=deoxit%2Caps%2C158&sr=8-4

When I received the charger, the charging lights were flickering. I should've returned it at that point but it still charged the battery. After using it about 20 times it stopped working. It won’t charge my battery anymore.

This BC-TRV charger has become my reliable power hub for all my Sony camera batteries. It handles everything from my compact NP-FP50 to the high-capacity NP-FV100, making it perfect when I'm switching between multiple Sony cameras. The compact design slips easily into my travel kit, and the included power cord works worldwide with the proper adapters. I appreciate how it charges each battery type at its optimal speed - my NP-FV70 charges in about 2.5 hours with no overheating. The LED indicator clearly shows charging status, and the build quality feels durable enough for regular travel. After a year of use, it continues to work flawlessly with all my Sony batteries. A must-have for photographers using multiple Sony bodies who want one universal charging solution.
